ES-D1008 is one of the models in Leadshine ES-D series easy servo drives which can take 20-80 VAC or 30-100 VDC input voltage, and output 0.5 - 8.2 A continuous load-based current. It is capable of driving NEMA 23, 24 and 34 easy servo motors (stepper motors with encoders) with the position loop closed in real time.
Based on latest DSP technology and adopting Leadshine's advanced control algorithm, ES-D1008 easy servo drive applies servo control on easy servo motors. When adopted with an easy servo motor, it combines features of both open loop steppers & brushless servo systems, and offers many unique advances features for excellent motion control system performance.
Same as servo drives in traditional brushless servo systems, an ES-D1008 easy servo drive takes encoder feedback from a driven ES-M series easy servo motor to close the position loop and eliminate the possibility of lose of movement synchronization. Therefore, loss of steps which limits adoption of stepper systems is totally eliminated in ES-D1008 driven easy servo systems. Compared with constant output current in open loop stepper drive, output current from an ES-D1008 servo drive to the driven motor is load based. When torque requirement is low, the output current is automatically lowered to the level of "just enough". But when the torque requirement is high, an ES-D1008 easy servo drive can boost the output current quickly, up to 8.2A. This can significantly improve control system response time, offer excellent acceleration performance, and reduce motor heating by as much as 50% over open-loop stepper systems. Also, there is no torque reservation needed for an ES-D1008 driven easy servo system. In an ES-D1008 driven easy servo system, it always allows 100% torque implementation available from the driven easy servo motor and thus improves system high speed performance by as much as 30% over comparable open loop stepper systems. In addition, smoothness and quietness are also significantly improved in ES-D1008 driven easy servo systems over steppers.
Compared with traditional brushless servo systems, cost for ES-D1008 driven easy servo systems is significantly lower. They also outperform comparable traditional brushless servo systems for the features of much higher low-middle speed torque, high standstill stiffness, no hunting (shaking), no overshooting, and almost zero settling time. In addition, plug-and-play setup for almost all applications makes ES-D1008 driven easy servo system much simple to set up, over hard-to-configure brushless servo systems which usual involve configurations of tens of parameters.
When an ES-D1008 easy servo drive is implemented with a Leadshine ES-M series easy servo motor, there is No Configuration Needed for almost all applications. The output resolution from ES-D1008 with the output resolution defaulted to output resolution of 2,000 pulses per resolution (equal to 10 microstep in 2-phase stepper systems). Via DIP switches, a user can also easily changes the output resolution to one of 15 output resolutions 800 to 51,200 (equal to 4-256 microstep in 2-phase stepper systems). With Leadshine configuration software, ProTuner, an advanced user can also set custom settings of resolution, current & position loop parameters, idle current percentage, etc.
ES-D1008 driven easy servo systems have been widely adopted by many Leadshine OEM clients to upgrade their open-loop stepper systems or replace brushless servo systems in industries such as CNC machineries, robotics, packaging, textile…
